Old NewNOTES:APF (As Reference in the Japanese seasonal performance benchmark for VRF)APF is meant for cooling/heating capacity per 1kW of operating power consumption under certain conditions throughout the year.APF = Accumulated cooling/heating loads (kWh) / Accumulated power input in cooling/heating (kWh)

NOTES:1. The graphs below show the EER/COP of single units for Oceania.2. The above values indicate the EER/COP per outdoor unit when it is combined with specified indoor units.3. The specification of EER/COP of each country is different according to the regulation. Please contact to the Sales person for more information.4. EER = Energy efficiency ratio = Cooling capacity or Heating capacity ÷ Power consumption of an air conditioner5. COP = Coefficient of performance of an air conditioner = Output KW (cooling capacity) ÷ Input KW (power consumption)

11Hz ~ 110Hz

990 Steps(by 0.1Hz)

15Hz ~ 100Hz85 Steps(by 1Hz)

The highly improved performance as well as greater energy saving is achieved by adopting newly developed high efficiency DC inverter compressor, with outstandingly precise control technology of 0.1Hz increments inverter frequency. Another feature is the dramatically extended working range, menabled by expanding the compressor’s operating frequency band, both upwards and downwards.

Smoother operation

The model calculates the appropriate amount of coolant supplied by the outdoor units on the basis of information about the required load from the individual indoor units. The model employs smooth operation control to control the number of revolutions of the inverter compressor. The model supplies the appropriate amount of coolant to the indoor units according to the required load. The model increases energy-saving efficiency by operating smoothly while controlling the switching on and off of the compressor at low-load operation.

Significant reduction of CO2 emissions

Significant reduction of power consumption

By reducing power consumption, we have significantly reduced CO2 emissions and reduced the environmental impact. (Reduction amount)

By increasing the performance of air blowers, heat exchangers and compressors and improving compressor control, we have significantly reduced annual power consumption. (Comparison of power consumption during a specific period)
